Definitions:

Node of Ranvier

Gaps in the myelin sheath of nerve fibers where the axonal membrane is exposed to the extracellular space, facilitating rapid signal transmission.

Action Potential

A rapid rise and subsequent fall in membrane potential across a cellular membrane, crucial for the propagation of electrical signals in nerve and muscle cells.

Local Potentials

Electrical changes in neurons that are confined to a small region, serving as the initial response to stimuli, potentially leading to action potentials.

Membrane Potential

The voltage difference across a cell's plasma membrane due to the differential distribution of ions.
